Innovation Solution
A system and method that utilize a processor to analyze physiological data in real-time, identifying diagnosis-enabling data and providing feedback through a user interface, including quality scores and navigation tools to improve data acquisition and ensure reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time analysis and feedback mechanisms are added to medical examination devices, then data quality and reliability are improved, but device complexity increases
Solution Approach 1:
The system implements real-time feedback by analyzing physiological data during acquisition and providing quality indicators to the user. The processor continuously evaluates data quality metrics and communicates feedback through the user interface, enabling users to adjust their technique immediately to improve data quality without requiring complex post-processing or repeated examinations.
Solution Approach 2:
The device performs self-evaluation of data quality by automatically analyzing the acquired physiological data and generating quality scores. The system serves itself by identifying poor quality data and prompting the user to recapture, eliminating the need for external quality assurance personnel or complex manual evaluation procedures.
2Measurement precision
If quality feedback mechanisms are implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system provides real-time feedback on data quality metrics including heart rate accuracy indicators. The processor analyzes the physiological signal and communicates quality information to the user through the display, enabling immediate correction of measurement technique to improve precision without adding complex external validation systems.
Solution Approach 2:
The patent replaces manual quality assessment with automated digital analysis. Instead of requiring trained personnel to evaluate signal quality or manually verify measurement accuracy, the system uses computerized algorithms to assess data quality and guide the user, substituting mechanical/expert evaluation with electronic automation.
3Ease of operation
If the device provides comprehensive quality indicators and navigation tools, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The device automatically guides the user through the data acquisition process by monitoring quality metrics and providing real-time instructions. The system self-evaluates the recorded data and communicates whether the measurement is sufficient, eliminating the need for users to understand complex quality criteria or manual evaluation procedures.
Solution Approach 2:
The system provides continuous feedback through the user interface regarding data quality and acquisition status. Quality indicators and navigation tools give users immediate information about whether their technique is adequate and what adjustments are needed, simplifying operation through informative feedback rather than requiring user expertise.

AI summary
A system comprising a processor configured to: obtain physiological data acquired during a medical examination of a patient's body, the medical examination being conducted by a user using a sensor, wherein the user is not a medical practitioner; analyze the obtained physiological data to determine presence of diagnosis-enabling data, wherein the diagnosis-enabling data enables a diagnosing entity to later diagnose a medical condition of the patient; and provide at least the diagnosis-enabling data, if present, to the diagnosing entity, thereby enabling the diagnosing entity to diagnose the medical condition of the patient.
